In 2013, observations of the ALMA radio interferometer revealed other features of the Boomerang Nebula.

Braude s research at the IRE centered on developing large-scale radio interferometers for precisely examining extraterrestrial radio sources.
4.
Some early radio interferometers operated as intensity interferometers, transmitting measurements of the signal intensity over electrical cables to a central correlator.
5.
In 1958 he demonstrated its effectiveness with a radio interferometer, but it only became widely used for long-baseline radio interferometry in 1974.
6.
LOFAR is a European radio interferometer, that measures radio waves with many individual antennas in different places which it combines to a single signal.

With the seven feeds it is also possible to detect structures which are too big to be seen with radio interferometers or single-pixel detectors.

On October 4, 1957, the very evening of the launch of Sputnik, students and faculty met at the Observatory and constructed an improvised radio interferometer.

*A solar radio interferometer operating at 17.5 MHz was installed with the help of the Soviet Union in 1970, and was reactivated in 1987.

In addition, a two-element radio interferometer based on the SIMPLE design is being constructed and will be used as a teaching instrument to expose students in astronomy labs to observations at other wavelengths.
